You should not have this issue from USB, suggests slow read speeds. Try another USB cable, re rip the game, etc, etc. This is common problem with backup disc, but USB should not give trouble. Try another ios to load the game. If that fails download a save game just past the castle. You should be able to find one, if not I can give you one.
